eXo Platform has introduced xCMIS, an open source implementation of the Content Management Interoperability Services (CMIS) specification that is compliant with the new CMIS 1.0 – cd06 specification and supports Java content repository (JCR).

The new offering works with third-party CMIS clients as well as a new eXo CMIS client based on Google Web Toolkit (GWT). The new GWT-based CMIS client offers the flexibility of building both standalone web applications and Google gadgets. The eXo CMIS client comes bundled in the xCMIS download, and will be accessible as a remote gadget leveraging GWT client libraries, the company claims.

According to eXo, the CMIS provides a common interface using either AtomPub or web services to enable content sharing across different content management systems. It enables developers to write new applications without concern for the development platform or language dependencies on any single content system as applications are no longer tied to any one specific content repository.

Benjamin Mestrallet, CEO of eXo Platform, said: eXo was founded on open standards, which remain core to our DNA. We started with the industry’s first Java portlet container, one of the first open source Java content repositories, one of the first enterprise OpenSocial implementations and now one of the most complete CMIS implementations available.

“In line with this commitment to open standards, we’re making xCMIS widely available as open source to ensure that any developer can have access to a first-class CMIS server with which to write their applications.

The xCMIS server is available as a community beta release with a production-ready version planned when the final CMIS 1.0 spec is ratified. Commercial support for xCMIS will be included in the next enterprise version of the eXo Platform, version 3.0, which will be based on GateIn.
